members of which are slitted for the pro- This invention relates to burners, and.

more particularly to burners for utilizing liquid or gaseous fuels or combustibles, such as hydro-carbon oils or gases or the like, and particularly to that class of burners designed, organized and' adapted for utilizing a mixture such as oil and steam or the like.

The invention has for its object to provide an improved burner of the general character above stated which will be superior in point of cleanliness of operation, freedom from smut and smoke production, completeness of combustion, economy of fuel units, high percentage of heat unit production, and facility of control, all combined with simplicity and inexpensiveness of construction and organization; and which will be generally superior in efliciency and serviceability, as well as adaptability to a wide range of use and service.

We are well aware that various burners have been devised and adapted for the mixture of. various elements with the fuel prior to the combustion of the same; but it has been a particular object of our experimenta tion, to which object we have attained as evidenced by extended periods of successful practice of the invention, to provide a burner which would cause or control combustion of the fuel with materially increased resultant heat values, and materially decreased or substantially obviated production of smoke and smut, to the end that an intense and highly caloric, as well as brilliant and clean flame, may be produced, with all the attendant advantages and factors of increased eliiciency.

According to the invention, we provide a burner having suitable supply means for the fuel and other ingredients or constituents, as, for instance, for steam and mineral oil. These ingredients are mlxed in'an elongated chamber which surrounds a steam chamber, and the ingredients are jection of the heated and mixed ingredients. Between these members of the burner end portion is disposed a steam duct or burner tip which constitutes the terminal portion of the steam chamber within the mixing chamber, and from which steam is ejected so as to comminglc with the mixed steam and oil jets ejected by the burner members, which are provided with slitted tips, causing fusion of the two jets of mixed or combined ingredients; all three jets merging at a common point beyond the termini of the burner'tips, at which point combustion is supported. y

The highly combustible generated by the mixed steam and oil under the violent merging of the three jets, support combustion accompanied by a brilliant flame which is approximately free from smoke and smut.

WVe have found that a burner organized and constructed in accordance with the above general provision, inter-relation and construction of parts, members and features, is of the highest efficiency and is accompanied in operation by marked fuel economy, when the heat units developed are taken into consideration.

The invention consists in the novel and useful provision, construction, organization, combination, association, inter-relation and general arrangement of parts, members and features, all as hereinafter described, shown in the drawings, and finally pointed out in claims.

In the drawings, Figure 1 is a top plan view, partly in section and partly broken awayfor clearness of illustration, of a burner constructed and organized in accordance with the invention; Fig. 2 is a front end elevation of the'burner; and, Fig.3 is

a vertical longitudinal sectional View, partly in section and partly broken away for clearness of illustration, of the burner illustrated in the other figures, and more fully disclosing the general organization and construction and interrelation of the parts and features thereof. This view is taken upon the line 3 3, Fig. 1. I

Corresponding parts in all the figures are denoted by the same reference characters. Referring with particularity to the drawings, A designates a burner organized in accordance with the invention and provided with oil supply means B and steam supply means 0. In the main, the burner A comprises three tubular and substantially or preferably concentric members a, b and c,

' the same being recitedin the order of their arrangement 1n enumeration inwardly toward the common center. The members a and c are substantially co-extensive longitudinally, being joined to constitute a burner tip portion 03 which comprises in turn three members f, g and h. The member 6 is relatively shorter than the tubular members a and c, terminating inwardly of the burner tip portion (Z. An annular chamber p sep- "arates the tubular members 6 and a, an annular chamber 70 separates the tubular members b and c, and an annular chamber m separates the tubular members a and 0 outwardly of the tubular member I), said chamberxm communicating with the chambers 79 and k. The tubular member 6 has a threaded connection with the inner end of the tubular member a, as at 4, and the tubular member a has a threaded connection with the inner end of the tubular member Z), as at 5, and likewise has a threaded connection with the outer end of the tubular member a, as at 6, intermediate of the members f and g and concentric with and communicating with the, member h; the members f and g and h of the burner tip portion 0? being preferably extensions of the tubular formation of the member a, which is enlarged to form said burner tip portion. The members f and 9 directly communicate with the chamthe membersf andg and is provided with a:

slitted tip 9 intermediate of the tips 7 and 8; the relative arrangement and disposition of the tips 7, 8 and 9 being such that the jets proceeding therefrom will merge at a common point outward of all of the three tips, and'the forces of all three jets will be united at that point, which will be the point at which combustion is supported. The slits in the several tips are elongated or relatively narrow, as clearly shown in Fig. 2. An oil supply pipe 10 is connected with the tubular member a at the inner end and laterally of the same, and may include aunion' joint 11 for purposes of assemblage and disconnection, The pipe 10 is also supplied with a valve casing 12 containing any su1table typeof valve having a stem 13 and hand wheel 14 to control the supply of Oll.

The oil supply means B are thus constituted. The. steam supply means C may comprise a main steam supply pipe 15 connected by unions 16 and 17; respectively with branch steam supply pipes 18 and 19 respectively,

which are respectively provided with valve casings 20 and 21; and the branch steam supply pipes 18 and 19 may include unions 22 and 23 respectively for purposes of as semblage and disconnection. The valve casings 20 and 21 include suitable valves controlling the pipes 18 and 19, such valves being provided with stems and hand wheels, a stem 24 and hand wheel 25 for the valve in they casing 20, and a stem 26 and hand wheel 27 for the valve in the casing 21. By manipulating the hand wheels 1 1, 25 and 27 the supply of oil in the first instance, and of steam in each latter instance, may be effectively controlled. The pipe 19 communicates with the tubular member I) at the inner end and. laterally thereof, and the pipe 18 communicates with the tubular member 0 at the inner end thereof. A union 28 may be provided for connecting the pipe 18 with the tubular member 0; and the several unions shown and described are of elbow, ring or othfir formation as best serves the purpose of eac It will be noted that the pipe 18 serves with steam the tubular member 0 leading directly to thetip 9; that the pipe 10 serves with oil the tubular member a, through the annular chamber p, then the annular chamber m leading directly to. the tips 7 and 8; and that the pipe 19 serves with steam the tubular member I) and the annular chamber It as well as the tubular member a and theannular chamber at leading directly to the tips 7 and 8. The steam issuing from the outer end of the annular chamber it mixes with the oil in the annular chamber m, surrounding the tubular member 0 which is heated by the steam within the same; and the mixture of steam and oil within the annular chamber 9%, under such thermal influence, passes to the burner tip portion (1, such annular chamber m serving as a mix- .ing chamber for the oil and steam which become intimately mixed within the burner tip portion 0?.

The resultant mixture is projected under pressure from the relatively narrow or elongated slits in the tips 7 and 8, and steam issues from the tip 9 of the same formation under expansive pressure. The convergence of the paths of projection of the mixed oil and steam jets and of the intermediate steam jet, due to the relative disposition of the tips 7, 8 and 9, causes the three jets or streams, to merge intimately, and a production of highly and freely combustible mixture ensues, and the spray from the steam tip 9 causes a complete mergenor-fusion of the mixed oil and steam-streams from thetips-7 tion d, and the mixture of steam and oil,

then traverses the members f and g of the burner tip portion and is emitted from the tips 7 and 8 thereof simultaneously with the emission of steam from the tip 9 of the burner tip portion member h.

The supply of oil to the mixing chamber m, and of steam to the mixing chamber m, through the annular chambers 72 and is respectively, may be regulated by the valves within the casings 12 and 21 respectively; and the supply of steam to the tubular member 0 may be regulated by the valve within the casing 20; so that the relative proportion of oil and of steam for the mixture, and of steam for the steam jet issuing fiom the tip; 9, may at all times be determlned, and so that the best working conditions may be determined and maintained, in accordance with the nature of surface to which the burner as an entirety is to be subjected.

It is manifest that We may depart in many respects from the specific showing in the drawings and the description in the specification,"in practising our invent-ion and carrying the same into operation and effect; and we do not desire to be understood as limiting ourselves to the particular construction, form, combination and inter-relation of parts, members and features as shown and described, but reserve the right to vary the same, in adapting the invention to varying conditions of use and service, without departing from the spirit of the invention and the terms of the following claims.
